 PincUay, F.E.G.S., read June 3, 1S67). The lat-

 miles, or a country as large as England and 

 France combined, enters Xvassa from the north. 

 Since that time Dr Livingstone has pkiced 

 (Letters to Dr Kirk, July 8, 1868, and to the 

 Earl of Clarendon, July, 1868) the Xile sources 

 between S. lat. 10° and 12% north of the great 

 Serra Muxinga of the Portuguese travellers

^ Mr Findlaj remarks, *The length of the J^ile's course 

 from Gondokoro to its mouth, following its major windins^s, is 

 about 2400 geog. miles (= 2780 British miles). From Gon- 

 dokoro, near to which it was generally agreed, ten years ago, 

 that the southernmost head of the Nile would be foimd, to the 

 south end of the Tanganyika Lake, is S30 geog. miles (= 960 

 Eritish miles). If the source be near the Muxinga range, it 

 must be 270 geog. miles (= 312 British mUes) still farther 

 south, so that its total course w-ill be 3500 geog. (= 4050 

 British) miles, almost unparalleled by any other river ' (loc. cit. 

 note, p. 16).
